Target

FunctionPlays a role in protein sorting and trafficking between the trans-Golgi network (TGN) and endosomes. Mediates the ARF-dependent recruitment of clathrin to the TGN and binds ubiquitinated proteins and membrane cargo molecules with a cytosolic acidic cluster-dileucine (AC-LL) motif.

Post-translationalmodificationsPhosphorylated by CK2 and dephosphorylated by PP2A (By similarity). Phosphorylation of GGA3 allows the internal AC-LL motif to bind the VHS domain and to inhibit the recognition of cargo signals.Ubiquitinated.
